Orchids in the genus ''Oncidium'' are tufted, [[Epiphyte|epiphytic]], [[Lithophyte|lithophytic]] or [[Terrestrial plant|terrestrial]] [[Herbaceous plant|herbs]] with clustered [[pseudobulb]]s each with up to four blunt-tipped, strap-like leaves.<ref name="FNA">{{cite web |title=''Oncidium'' |url=https://floranorthamerica.org/Oncidium |publisher=Flora of North America |access-date=24 November 2025}}</ref><ref name="ABC">{{cite web |title=''Oncidium'' |url=https://www.abc.net.au/gardening/plant-finder/oncidium/9441886 |publisher=Australian Broadcasting Corporation |access-date=24 November 2025}}</ref> The [[inflorescence]]s are borne in [[panicle]]s, usually appear from the axils of recently matured growth and flower only once from the pseudobulb.

The fruit is a [[Capsule (fruit)|capsule]].<ref name="FNA">{{cite web |title=''Oncidium'' |url=https://floranorthamerica.org/Oncidium |publisher=Flora of North America |access-date=24 November 2025}}</ref><ref name="ABC">{{cite web |title=''Oncidium'' |url=https://www.abc.net.au/gardening/plant-finder/oncidium/9441886 |publisher=Australian Broadcasting Corporation |access-date=24 November 2025}}</ref>
This genus was first described by [[Olof Swartz]] in 1800 with the orchid ''Oncidium altissimum'', which has become the type species. Its name is derived from the Greek word ὀγκος, ''onkos'', meaning "swelling". This refers to the callus at the lower lip.


Most species in the genus are [[epiphytes]] (growing on other plants), although some are [[lithophyte]]s (growing on rocks) or [[terrestrial plant|terrestrials]] (growing in soil). They are widespread from northern [[Mexico]], the [[Caribbean]], and some parts of South [[Florida]] to South America. They usually occur in seasonally dry areas.
==Taxonomy==
 
The genus ''Oncidium'' was first described in 1800 by [[Olof Swartz]] in ''Kungliga Svenska Vetenskapsakademiens Handlingar'' (''Proceedings of the Royal Swedish Academy of Sciences'')<ref name="PoWO">{{cite web |title=''Oncidium'' |url=https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:331250-2 |publisher=Plants of the World Online |access-date=24 November 2025}}</ref><ref name="Swartz">{{cite journal |last1=Swartz |first1=Olof |title=''Oncidium'' |journal=Kungl. Svenska vetenskapsakademiens handlingar |date=1800 |volume=21 |pages=239–240 |url=https://www.biodiversitylibrary.org/item/180980#page/261/mode/1up |access-date=24 November 2025}}</ref> The genus name ''Oncidium'' is derived from the Greek word ὀγκος, ''onkos'', meaning 'swelling' and the [[diminutive]] ''-idium'' in reference to the prominent lip [[Callus (botany)|callus]].<ref name="FNA" />
They can be divided into three categories, according to their growth pattern:
* Some have green [[pseudobulb]]s and long [[raceme]]s with small flowers and a dominant [[Labellum (botany)|lip]]. They are mostly golden yellow with or without reddish-brown barring, but some are brown or yellowish-brown. Other ''Oncidium'' species have white and pink blooms, while some even have startling, deep red colors in their flowers.
* Another group has extremely small pseudobulbs and stiff, erect, solitary [[leaf|leaves]]. These cylindrical leaves act as a water reserve. They have long racemes with yellow flowers that seem to fan out at the top. Sizes of these orchids can vary from miniature plants of a couple of centimetres to giants with 30&nbsp;cm-long leaves and racemes of more than one metre long. These species, known as the Mule-Ears, are now classed as ''[[Psychopsis]]''.
* Formerly there was a third group, called the Variegata or equitant oncidiums. They have no pseudobulbs, giving fan-shaped shoots of less than 15&nbsp;cm, with triangular section leaves. These oval, broad and spongy leaves act as storage organs. Their flowers are most complicated with exquisite colors. The sepals are somewhat fleshy. The petals and the lip are membranaceous. These orchids are now classified as ''[[Tolumnia (plant)|Tolumnia]]''. ''Cyrtochilum'' is another [[genus]] that many ''Oncidium'' species have been reclassified into; ''Cyrtochilum'' species have extremely long, winding inflorescences that can sometimes reach 20' or more, curled petals that result in three-pointed blooms, and rambling growth habits in which each new pseudobulb appears on top of the old one.
 
''Oncidium'' species are characterised by the following properties :
* presence of [[column (botany)|column]] wings,
* presence of a complicated callus on the [[Labellum (botany)|lip]] (this can be used to separate the taxa),
* [[pseudobulb]]s with one to three leaves,
* several basal [[bract]]s at the base of the pseudobulbs.
 
The [[flower]]s come in shades of yellow, red, white and pink. The petals are often ruffled on the edges, as is the [[Labellum (botany)|lip]]. The lip is enormous, partially blocking the small petals and sepals.
 
Some ''Oncidium'' orchids are very tall: ''[[Oncidium altissimum]]'' and ''[[Oncidium baueri]]'' can grow to a height of 5&nbsp;m.
 
They are known as 'spray orchids' among some florists. They are very varied and are easily hybridised with other closely related genera forming the ''Oncidium'' alliance (''Miltonia'', ''[[Cuitlauzina]]'', ''[[Miltoniopsis]]'', ''[[Leochilus]]'', ''[[Comparettia]]'', ''[[Cyrtochilum]]'', ''[[Tolumnia (plant)|Tolumnia]]'', ''[[Rhynchostele]]'' [formerly ''Lemboglossum''], ''Psychopsis'', etc.). Some of the best ''Oncidium'' alliance hybrids originate from ''[[Oncidium tigrinum]]'' and ''[[Oncidium incurvum]]'' when crossed with species formerly placed in ''Odontoglossum'', although hybridization possibilities of this group of orchids are endless, and there are literally hundreds of thousands of hybrids in the ''Oncidium'' alliance.

Template:Short description Template:Automatic taxobox

Oncidium is a genus of about 370 species of orchid in the family Orchidaceae. It is distributed across tropical and subtropical America from Mexico, Central America and the West Indies to northern Argentina, with one species (O. ensatum) extending into Florida.[1][2] Common names for plants in this genus include dancing-lady orchid.[3]

A molecular phylogenetic study published in 2009 labeled the Oncidium alliance "grossly polyphyletic."[4] In the same year, the American Orchid Society labeled the genus a "dumping ground".[5] A consensus announced in April 2013 resulted in major taxonomic changes to Oncidium, Gomesa, Odontoglossum, Miltonia, and others.[6] Much of this debate and subsequent housekeeping was initiated by significant research for the scientific publication Genera Orchidacearum Volume 5.[7] One significant change is the move of most Brazilian Oncidium with a fused lateral sepal to the genus Gomesa.[5][4]

Description

Orchids in the genus Oncidium are tufted, epiphytic, lithophytic or terrestrial herbs with clustered pseudobulbs each with up to four blunt-tipped, strap-like leaves.[8][9] The inflorescences are borne in panicles, usually appear from the axils of recently matured growth and flower only once from the pseudobulb. The flowers are resupinate, the sepals and petals free from each other, egg-shaped to nearly circular, with a fiddle-shaped lip with a prominent warty fringe. The fruit is a capsule.[8][9]

Taxonomy

The genus Oncidium was first described in 1800 by Olof Swartz in Kungliga Svenska Vetenskapsakademiens Handlingar (Proceedings of the Royal Swedish Academy of Sciences)[10][11] The genus name Oncidium is derived from the Greek word ὀγκος, onkos, meaning 'swelling' and the diminutive -idium in reference to the prominent lip callus.[8]
